Clips Retain adjust time between deletions

[Jurykov]

My frigate instance is running in a docker image on an Unraid server. The clips directory is written to a flash based cache disk as clips are recorded, then once per day, Unraid will automatically move the recorded clips to physical spinning disks for long term storage. These disks spin down and go to sleep in order to save power/heat/noise, and normally are only woken up during the daily move, or when I try to access older files.

Frigate looks like it's checking for clips for deletion every 10 minutes. This is causing the physical disks backing my cache to never go to sleep as they are constantly being woken up by the Frigate process. I suppose I also have the issue of the database being stored in the clips directory which would cause the disks to be constantly woken up as well.

It would be nice to be able to configure the period of the deletion of old clips e.g. hourly, daily, weekly, # days, etc. Also, it would be nice to change the folder to where the database is stored (I would keep it in the same folder as the config files, but it would probably be better if it wasn't hard coded).

I love using Frigate! It's a huge improvement to what I was using before, and really lowers the resource requirements of my server. Currently I just keep everything on the cache disk and it's working great, but I would be able to greatly increase the length of time I keep older clips if I could move everything off of my small cache, and keep it in my much larger storage array.

Thanks for all your hard work on this!
